I bought the Hollywood Camera Work DVD course (see: Hollywood Camera Work - Film School, Film Directing, Filmmaking, Cinematography) a couple of years ago. I learned a lot from it, and use it for reference. This same company has just released a new 7-DVD course on Special Effects. There is a Trailer about the new course and an outline at this link:Visual Effects For Directors Pre-Order
I'm placing this "pimp" endorsement on this forum because the guy who produces these courses, Per Holmes, has really put out some great material that is worth the price. Even those with lots of filmmaking experience can learn something new from this director's tutorials.
By the way, I have also purchased the new Effects course and took advantage of the introductory discount he is offering. Anyway, check it out.
